WINDING MACHINE FOR RECORDING PAPER.

Application filed October 19, 1922 Serial No. 595,553.

To all whom it mag concern:

Be it known that I, FREDERlGK Lnnrono, a citizen of the United States,residing at Portland, in the countyof Multnomah and State of Oregon,have invented a new and useful lNinding Machine for Recording Paper, ofwhich the following is a specifica- Dion.

My invention relates to winding machines for recording paper, in whichthe factory roll, i. e. the roll of recording paper as furnished by theprinting factory,is rotatably supported at one end of the machine, andrewound at the other end on the so-called supply roller, ready for usein a recording machine.

To a better understanding of this invention it maybe mentioned that thefactory roll contains a strip of paperpossibly 1500 yards. in length,whereas a recording machine requires only about 25 or 50 yards. Further,due to lateral swaying ot' the paper as the latter is sent through theprinting roller, the longitudinal lines on the paper are never straight,but will sometimes deviate from a straight course by as much as one inchor more toward either side, while for recording purposes the lines mustrun absolutely true. j

The objects of myin-vention are First, to rewind the paper in suitablelengths for a recording machine.

Second, to produce recording paper in rolls, with the lines running truefor recording purposes.

Third, to produce an apparatus by means ofwhich the recording paper canbe rolled true for the purposes above mentioned.

Fourth, to produce an apparatus which is comparatively simple inconstruction and easy to manipulate. v

Further objects and advantages will be pointed out at appropriate placesin the specification and particularly in the appended claims.

I attain these objects with the mechanism illustrated in theaccompanying drawings, in which 1 ,Fig.1 is a plan view of the entirepparatus with the paper omitted.

Fig. 2 is a side elevation of Fig. 1.

Fig S is a vertical, longitudinal section along the center line ofFig.1, illustrating the course taken by the paper strip.

background.

Fig. 5 is a detail of the front pointer.

Fig. 6 is a portion of the supply roller, showin the core, the paper onthe core and the was er. 7

Similar numerals refer to similar parts throughout the several views.

On each side there is a rail 1 resting on the, legs 2. Both sides areheld together by twoflstay bolts 8 at the bottom of the legs, one staybolt'4c through the rails midways between the legs, one stay bolt 5 atthe rear end of the rails, and one stay bolt 6 at the frontend.-.Slidably mounted in the rails 1 above the stay bolt 5 are two rods 7which are rigidly connected by a bridge 8. By means of a lever 9, whichengages the bridge with the pin 10 (Fig. 3), said bridgeand therewiththe rods '7 can be shifted-in lateral direction. One end of the lever isfulcrumed in the bracket 11, whichlatter is attached to the stay bolt 5,while theother ally retains a fixed position on therods,

the latterlhowever, can be shifted according to the length of thefactory roll. 14 which is supported between the center points 15 and 16in the brackets. From thetactory roll the recording paper 17 is led overthe idler 18 past the rear pointer 19 (Fig. 4). The rear pointer isslidably attached to the angle bracket 20, in order to adjust itself tothe altitude of the paper as'the factory roll diminishes in size from adiameter of about 9 or 10 inches while new, to about 2 or 3 inches whenthe last layer is unwound. For auxiliary adjustment the leg of the anglebracket where it attaches to the side rail is slotted as indicated at21..-.Thereatter the recordingpaper is led underneath the idler 22 andover the idler 23 to impart tension to the recording paper. For furthertension the paper is led underneath the idler 24, and over the idler 25.At this point the paper is pressed upon by a rubber covered roller 25which latter is guided in slots 26 in the side rails. By means of therubber covered roller, the paper can be shifted to one side or theother. To facilitate the shifting, a hand lever 27 is fulcrumed at 28toward the left and at the outside of the rail. From the idlerthe'recording paper is led underneath the idler 29 and past the frontpointer 30. This front pointer is mounted on a rod 31 between the siderails and is capable of adjustment in lateral direction for accuratesetting on some particularly chosen line. From the idler 29 the paper isled on to the core 32 of the supply roller (the name supply rollerrefers to the ultimate function of supplying the paper in a recordingmachine).

The supply roller has one end mounted in the center point 33 on thebracket 34, and

the latter is adjusta-bly attached to the rods 35. The other end of thesupply roller core has a hole 35 (Fig. 6), is supported in thecenterpoint 36, and carried around by a carrier pin 37 in the spindle88. The spindle is mounted in the bearing 39 in the side rail andmanipulated by means of the crank 40.

lVhile the operator is turning the crank he must closely observe thefront pointer and instantly correct any deviation of the paper from thetrue course by manipulating the hand lever 27. He must also cast anoccasional glance at the rear pointer and correct any deviation from thetrue course shown there by shifting the factory roll by means of thelever 9.

After the supply roller has been wound with recording paper of therequired length the uneven edges of the paper are cut smooth and true ina lathe, a washer 41 is placed over the core against the paper edges andthe supply roller is ready to be packed for shipment without danger thatthe alinement could accidentally be disturbed.

Having thus described my invention, it will be seen that my objects havebeen accomplished, and, though I have shown the preferred form ofconstruction, I reserve to myself the right to make minor changesproviding I do not violate the spirit and principle of my invention.

So far as I am aware I am the first one to produce strips of recordingpaper in rolls, and I am therefore entitled to claim the machine per se,well as the method and the product.

I claim:

1. In a winding machine for recording paper, the combination with afactory roll, of manually operated means to wind said paper on a supplyroller, and means to observe the alinement of the longitudinal crosssection lines irrespective of the marginal alinement of the paperitself.

2. In a winding machine for recording paper, the combination with afactory roll, of manually operated means to Wind said paper on 'a supplyroller and adjustable means to check the true alinement of thelongitudinal cross section lines irrespective of the marginal alinementof the paper itself.

In a winding machine for recording paper, the combination with a factoryroll, of relatively movable supports for said factory roll, a supplyroller rotated by a crank, a relatively movable support for one end ofthe supply roller, tension-producing idlers between the factory andsupply roll, and means to check the true course of the paper over saididlers, said means comprising front and rear pointers.

a. In a winding machine for recording paper, the combination, ofmechanism for winding said paper, with front and rear pointers forchecking the true course of the paper, and means for correction ofdeviations from the true course.

5. In a winding machine for recording paper, the combination with afactory roll, of a supply roller, and means to wind the paper in truealinement on the supply roller,

said means including normally stationary front and rear pointers, acrank adapted to rotate the supply roller, and an axially movable rubbercovered roller extending throughout the width of the paper adjacent thefront pointer.

6. In a winding machine for recording paper, the combination with afactory roll rotatively mounted and having a relative movement in axialdirection, of a supply roller, and means to wind the paper in truealinement on the supply roller, said means including adjustable frontand rear pointers, and a lever cooperatively connected with the factoryroll and extending to the front end of the machine.

7. In a winding machine for recording paper, the combination of two siderails, a factory roll mounted at one end of the side rails, a supplyroller mounted at the other end of the side rails, idlers between thetwo side rails, a front pointer adjacent to the supply roller, and arear pointer adjacent to the factory roll, both pointers checking thetrue alinement of the paper between the factory roll and the supplyroller.

8. In the method of winding recording paper in true alinement, the stepsof mountii I the factory roll rotatably, of adjust- 11 out and rearpointers to suitable longitudinal cross section lines on the paper, ofwinding the paper manually on a supply roller core, and of checking thecourse of the paper between the factory roll and supply roller core bymeans of the pointers.

9. In the method of winding recording paper in true alinement, the stepsof mounting the factory roll rotatably, of winding the paper manually ona supply roller core, of producing tension in the unwinding paper, andchecking the course of the paper by means of pointers disposed on theupper surface of said paper between the factory roll and the supplyroller core.

10. In the method of winding strips of recording paper in truealinement, the steps of mounting the factory roll rotatably, of windingthe paper manually on a supply roller core, of mounting a rear pointerover the paper adjacent to the factory roll. and correcting the courseof the paper by shifting the factory roll.

In the method of winding strips of recording paper in truealinement, the steps of mounting the factory roll rotatably, of Windingthe paper manually on a supply roller core, of producing tension in thepaper before reaching the supply roller core, of mounting a frontpointer over the paper adjacent to the supply roller core, and correcting the course of the paper immediately preceding the supply rollercore.

12. In the method of winding strips of recording paper in truealinement, the steps of winding said paper from a factory roll onto asupply roller, of producing tension in the unwinding strip, of checkingthe course of the paper by means of a front and rear pointer, ofshifting" the factory roll laterally for correction with the rearpointer, and shifting the paper strip by means of a rubber coveredroller for correction with the front pointer.
